Alternatives to Towns
Seeing the failure of Towns is something that has damaged a lot of people, and also their pockets. However, Towns was not an unique game. Being based mostly in dwarf fortress, you can find two projects that are, in my opinion, the most suitable substitutes.
The first is a game called Gnomoria. It is available right here in Steam, and by half of the price of Towns. Despite its retro graphics (but you wouldn't be reading this if you minded about graphics, wouldn't you?) the gameplay is deep and full of posibilities, with a challenging (customizable) difficulty that provides a lot of entertainment and all the world customization you would like to encounter in a game of this genre. If you have played dwarf fortress, this is your game. I highly encourage you to try it out (70 hours into the game are quite something).
The second is Stonehearth. Although the name is quite similar to Blizzard's latest card videogame, it has nothing to do with it. Right now is being developed by Radiant Entertainment, a little company founded with this project. They were blessed by a greatly succesful kickstarter campaign, which has allowed to them to keep the project going for a year, until the present day. Weekly updates on a game of 3d graphics with an old Zelda-bit art style that is promising to become the next dwarf fortress. Tons of classes, procedural world generation, infinite posibilities of crafting, customizable buildings, world manipulation, varied enemies, from zombies to huge titans and wrathful elementals, magic, trading, three human playable races (I say humans, because eventualy we will have... DWARVES! Everyone loves dwarves, right?) complex AI and NPC behaviour, and a master mind that watches your actions and decides what is the best event to react to them (unprotected stockpile? Don't mind if I send some raiders) and last but not least, complete mod support, and friendly, too. I may add that the developers are extremely active with the community, and that is always a plus. The moment they shut, the moment you should start to worry.
That have been my recomendations. I hope they help you to overcome the tough situation Towns has putted you in. Goodbye, and keep playing!
